About to complete ongoing repair of bay window, ready to cut and
install the siding. The longest "wall" is 42 inches. How much room
should I leave (if any) between siding and cornerboards?

Masonite and wood have fairly similar expansion rates with changes in
temperature and humdity, so a close fit should be OK. HTH
My masonite siding has several places where it is buckled due to too tight
installation. I do not know what the original installer did but I like to
leave about 1/8 inch gaps. I think this makes it much easier to get a good
caulking bead to both seal well and prevent buckling. Flashing under the
joints also provides extra protection against water infiltration.
